AUTOMATIC DRAININ'G DEVICE.

Application filed January 11,1917.

To all whom it may concern:

Be it known that 1, JOHN DONALD Wooo- WORTH, a citizen of the UnitedStates, residing at East Moline, in the county of Rock Island and Stateof Illinois, have invented certain new and useful Improvements inAutomatic Draining Devices; and I do de clare the followingto be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to draining devices to be used more particularlyin draining cellars, sewers, and other excavations without attention bythe user.

This invention has for one of its objects the provision of afloat-operated injector mechanism which will become operative when thewater lever in the cellar, sewer, or other excavation rises to apredetermined point.

Another object of the invention is to provide a device of this characterin which the various parts are arranged in a very neat and compact form.

A further object of the invention is to generally improve upon devicesof this character by the provision of a simple, strong, durable, andcomparatively inexpensive construction, and one which will be eflicientand reliable in operation, and well adapted to the purpose for which itis designed.

With these and numerous other objects in view, the invention consists ofcertain novel features of construction, and the combination andarrangement of parts as will be hereinafter fully described andclaimed.

In the accompanying drawings forming a part of the application, and inwhich similar reference characters designate like parts throughout theseveral views:

In the embodiment illustrated, the reference numeral 1 designates avertical suction pipe adapted to be disposed in a cellar, sewer, orother excavation wherein the water to be drained ofl collects. To thelower end of this suction pipe 1 there is connected a strainer 2', thelatter being made in two separable sections 3 and 1, the section 3 beingthreaded to the pipe 1 as shown, while the section 4 is perforated as at5 and provided with legs 6 to maintain said strainer in slightly spacedrelation with respect to the bottom of the cellar or other excavation.The sections 3 and 4 are circular in configuration and are provided withangular flanges 7 and 8 respectively between which is clamped asubstantially flat plate 9, the central portion of which is providedwith an opening 10. Seated upon the plate 9 and slidably mounted withrespect to the open ing 10 is a valve member 11. When this valve member11 is in its lowermost posi tion no water will pass from the strainerinto the suction pipe 1, but as soon as the member 11 ismoved upwardlyunder the suction created in the pipe 1, the Water is allowed to passthrough the strainer into'the latter.

The upper end of the suction pipe 1 is threaded to the laterallyprojecting portion 12 of a hollow housing 13.- This housing 13 is verysimilar to: a T coupling, and has its vertically disposed portion 1aarranged out of vertical alinement with the pipe 1. Threaded to theupper end of the vertically extending portion 14 of the housing 13 is adischarge pipe 15, while similarly secured to the lower end of theportion 14 is the stem 16 of an injector nozzle 17. It may well be notedthat the injector nozzle 17 is disposed in vertical alinen'i'ent withthe dischargepipe l5,. and that the latter is disposed outv of alinementwith the suction pipe 1 and has its low-er end arranged in a planespaced a short distance above the plane of the upper end of the latter.The reference numeral 18 designates a short length of pipe which isthreaded to the upper end of a vertically extending portion of thehousing 13 and is arranged centrally with respect to the discharge pipe15. This pipe 18 has its lower end flared and disposed adjacent the freeend of the nozzle 17 to coact with the same tically through the lowerend of the portion 14 of the housing 13 and is formed into a valvecasing 19, one side of which is con nected to one end of a supply pipe20, the, purpose of which will be hereinafter de scribed.

Mounted within the valve casing 19 is a vertically slid'able valve 21,which, when in its uppermost position, seats itself against the upperend of the casing and prevents the fluid supplied by the pipe 20 frompassing up through the stem 16 and out through the nozzle 17. lVhen thevalve 21 is in its lowermost position it is opened, and such fluid maythen be allowed to pass through the nozzle.

The reference numeral 22 represents a vertically extending stemconnected in any suitable manner to the valve 21. This stem 22 projectsdownwardly through a packing box 23 arranged in the lower end of theeasing 19, and is arranged alongside of and parallel with the suctionpipe 1 as shown.

Slidable vertically upon a portion of the suction pipe 1 disposed belowthe plane of the lower end of the valve stem 22 is a float 24. Thisfloat is preferably in the form of a hollow cylindrical casing having acentrally arranged vertically extending tubular opening 25 therein. Thetop of the float 24 on opposite sides of the pipe 1 is provided withpairs of pivot ears 26, to which are pivotally mounted the lower ends ofa pair of links 27.

The upper end of the links 27 are similarly connected to the free endsof the arms 28 of a forked lever 29. The other end of the lever 29 ispivoted to the upper end of a bracket 30 which extends from the side ofthe valve casing 19 adjacent the pipe 1. This bracket 30 extends in asubstantially vertical direction and has pivotally connected to itslower end a link 31, the free end of which is pivotally connected to theintermediate portion of a lever 82. One of the ends of this lever 32 isconnected to the lower end of a link 33, the other end of which issimilarly connected to the lever 29 at a point spaced a short distanceinwardly of its connection with the bracket 30. The other end of thelever 32 is pivotally connected with the lower end of the valve stem 22.By this construction it may be seen that whenever the float 24: israised, the valve stem 22 will be lowered and consequently the valve 21will be opened, thereby permitting water, steam, or other fluid underpressure to pass upwardly through the stem 16 of the nozzle 17, then outof the nozzle into the pipe 18. This causes a suction in the housing 13and also in the pipe 1 suflicient to raise the valve member 11 and allowthe water contained in the excavation in which the device is placed tobe drained away. The movement of the float 24 is obviously caused by thechange in the water level in the excavation, and it therefore followsthat when this level is lowered to an amount ,where no harm will bedone, the valve is closed.

From the foregoing description, taken in a As various changes in form,proportion and in the minor details of construction may be resorted towithout departing from the spirit of the invention, I do not wish to belimited to the construction herein shown and described other than thatset forth in the appended claims.
